ASTRID opened the door to his apartment as he checked the comments of the post he posted on [Cyberspace] during lunch. Ellis told him to post something to show his fans that the ordeal last night didn't affect him at all. So, he posted his lunch. He only now had the time to check people's response to it.
It's because as soon as his afternoon class ended, his parents called him. Just as he expected, the two found out about that Nadia Beck issue and immediately checked on him.
Funny thing was, because the issue had already passed when they woke up, the didn't find about it until later when he posted that picture on [Cyberspace] and read the comments of his fans encouraging him and asking him if he's alright. They probably waited until he finished his afternoon class before calling him.
